Description

1 TARIFF MIXTURE QUALITY IMPROVED WITH VARIABLE SPEED STARS. CONCRETE PRODUCTION MIXER Technological Field: This invention is designed for use in the ready-mixed concrete industry and for the preparation of concrete. During this stage, the sand, gravel, cement, and water it contains move in two different directions. Variable 10, whose kinematics aim to mix to a homogeneous consistency in a short time. It relates to rotary concrete production mixers. State of the Art: Today, road construction, landscaping, building projects, and infrastructure projects are all part of the 15th century. Concrete is commonly used in repairs. Concrete consists of cement, sand, gravel, and It is obtained by mixing water in specific proportions. Concrete is prepared by mixing concrete. mixers (planetary, twin-shaft, single-shaft, pan mixers) or vehicles called transit mixers It is needed. In concrete mixing systems called pan mixers, the materials are generally placed in pans (bowls). The contents are poured into it. Generally, the materials are found in large bowls. The ingredients are mixed using mixing paddles and scraping blades. In these mixers... The problem is this: the mixing paddles are performing a translational motion without mixing. It takes quite a long time for the concrete quality to reach the desired consistency after they do this. 25 Because mixing paddles can quickly scan every point where the mixture is located. This is not the case. This situation is particularly problematic in terms of efficiency and speed in large construction projects. This can lead to limitations and compromises in concrete quality. Planetary mixer systems use planetary mixers for concrete mixing. These mixers are used. They rotate both around their own axis and at the center. They perform the area scanning operation by rotating their shafts. 2 Some planetary gears also have horizontal movement. In these systems... The shortcomings are the unsuitable positioning of the planetary mixers and the insufficient number of arms. Due to its smaller size, scanning the entire area within the dish is possible compared to pan mixers. It takes quite a long time. Patent application US4758095A describes a double-shaft pan mixer. A double-shaft pan mixer is a mixing unit with a first and a second pan section. The containers are arranged horizontally and parallel to each other inside the mixing bowl. drive system installed and adapted to rotate in opposite directions a pair of track assemblies with shafts and synchronized drive of the pair of track assemblies 10 It includes a drive source to operate it. The mixing bowl consists of first and second bowl sections. under an area between them and shifted outside the turning points of the rowing mechanisms, largely a triangular void and also one placed adjacent to the void It includes a discharge section. The mixer is also located inside the cavity and driven by shafts. It includes a rod-shaped vibration generator extending in a parallel direction. 15 The double-shaft pan mixers described in the above patent application are double planetary. They can also be called mechanisms. These mixers are more versatile than other pan mixers. They are complex and customized machines. These machines involve a single movement. This movement is achieved through mixers connected to two different shafts. (Source 20) The document in question does not include scrapers; it refers to the parts of the materials that stick to the drum. It cannot be cleaned, the materials cannot be mixed effectively, and A homogeneous mixture cannot be obtained. Patent application number GB2053706A describes a concrete mixer. The invention is a horizontal 25 a mixing bowl positioned as such and mounted on a bearing by a shaft It includes a rotor. The rotor has related rods, one directly connected to the rotor and the other to the shaft. driven by two motors via couplings and speed reduction transmission units. The units are framed with torsion bars to prevent the shaft from bending. It is connected. 30 3 The concrete mixer described in the above patent application is also known as a pan mixer in the industry. It is known that the problem with these machines is that the pallets do not improve the quality of the concrete mixture. The ability to make it suitable over periods much longer than the targeted times. In conclusion, a new 5 that can overcome the disadvantages mentioned above. Technology is needed. Description of the invention: Our system, which is the subject of this invention, is designed for use in the ready-mixed concrete industry and consists of 10 The sand, gravel, cement, and water to be included will be processed using two different kinematics of motion. It relates to concrete production machines used for mixing purposes. The difference between our system and similar machines on the market is that the mixing materials are processed in a shorter time. By ensuring better homogenization in a shorter time, a superior quality concrete mixture is obtained. 15 The difference lies in facilitating the scanning of a wide area within our system. Arms that perform translational (or sweeping) motions and mixing in a confined space. It is formed by the function of the other arms that perform the movement. In short, the arms in our invention It creates a complete scanning area. The motor in our invention is inverter-controlled, and the mixing speed can be adjusted to the desired speed. It is adjustable. The mixing arms can rotate at the desired angular velocities, and this This allows the concrete consistency to be adjusted and homogenized quickly. It helps. Our invention enables the production of high-quality concrete in a shorter time. It provides the opportunity for fast and high-quality concrete production in construction projects where this is required. 25 This provides an advantage. The ability to adjust the rotation speed allows for more precise quality. Control is ensured and customer satisfaction increases. In addition, inverter controlled. Motors make the concrete mixing process more automated, reducing labor requirements. By reducing and operating motors at variable speeds, energy efficiency is increased and the operation Costs are decreasing. 30 4 Explaining the Figures: The invention will be described by referring to the attached figures, so that the features of the invention can be explained.

All the elements forming the system shown in Figures 1-2 are inside the main body (1) located under the main body (1) are the lower motor (2) and lower gearbox (3). The upper motor (10) and the upper gearbox (11) are located on the main body (1). Upper 30 The turntable is powered by the gearbox (11), the upper gearbox output shaft (12) and the intermediate bearing (14). 6 (4) is integrated onto the main body (1) which is a mixture of sand, gravel, cement and water. It is kept and mixed inside. Our invention utilizes two different motion kinematics in its mixing process. The first of these is translational motion, and the other is mixing motion. Main body (1) 5 horizontal mixing arm (5), vertical mixing arm (6), horizontal outer scraper arm (7), inside The pallets are attached to the ends of the vertical outer scraper arm (8) and inner scraper arms (9). It translates with the help of. The term translation refers to the mixture in our invention applied to a wider area. It means to mix by spreading. The translational motion is also expressed as a sweeping motion. These arms (5, 6, 7, 8, 9) are fixed to the turntable (4) and connected to the lower motor 10 (2) the associated lower reducer (3) enables the circular movement of the turntable (4) and the arms (5, Arms (5, 6, 7, 8, 9) move in the same direction. This movement of the arms (5, 6, 7, 8, 9) blending the mixture by sweeping or shifting it from one point to another. It provides. The position of the arms (5, 6, 7, 8, 9) on the turntable (4) is from the center outwards. It will be such that the arm fixed near the center of the turntable (4) is 15 short length horizontal mixing arm (5) and vertical mixing arm (6) close to the center While shifting the mixture in the region, the horizontal mixer arm (5) with a long arm length and the vertical The mixing arm (6) shifts the mixture at the point furthest from the center. Similarly, the horizontal outer scraper arm (7) and vertical outer scraper arm (8) to the outer wall of the main body (1) of the mixture While preventing adhesion, the inner scraper arm (9) pushes the mixture 20 to the inner wall of the main body (1). It prevents sticking. The scrapers clean the inner surface of the drum while simultaneously removing the concrete. sediment and adhering materials that prevent the mixture from mixing properly They also undertake the task of extraction. The second step is mixing. This mixing process involves mixing the concrete in a smaller area, 25... This ensures a more homogeneous blending. The mixing process in a confined space uses a star shape. It is performed with vertical arms (24) attached to plates (23). There are three arms in a star plate (23). There is a vertical arm (24), but the number of units must be at least one. It can be adjusted. The star plate (23) is attached to the bottom of the turntable (4). and the arms (5, 6, 7, 8, 9) move while the turntable (4) rotates in a circular manner. 30 During this time, the star plate (23) rotates together with the turntable (4) and at the same time it rotates on its own It also performs circular motion around its axis. These axes of motion are shown in Figure 4. 7 In the image, these are shown as the y1 and y2 axes. The arms that enable the translational movement. (5, 6, 7, 8, 9) receive their drive motion from the lower motor (2) and lower gearbox (3), while the star plate (23) and the vertical arms (24) attached to this plate drive the movement of the upper motor (10) and the upper It receives power from the motor reducer (12). The upper motor (10) is inverter controlled and vertical. It can enable the arms (24) to move at variable speeds. 5 Figure 4 shows the arms (1) in the main body that perform both translation and mixing operations. A detailed view of the mechanisms to which they are connected is given. Upper motor (10) and upper the reducer (11) through the y1 axis to the rotary table (4) via the reducer output shaft (12) It is connected. The upper gearbox output shaft (12) connected to the motor gearbox (11) has a torque of 10 power, bearing (14) and adapter (13) that enables variable motion transmission It transmits the power to the hub where the main gear (15) is located. The main gear also transmits the power to its teeth (15). It transmits the torque it receives to the associated pinion gear (16). The pinion gear (16) rotates At the moment of starting, the chain sprocket fixed concentrically on the same shaft (17) It starts to move. The sprocket (17) transmits the rotational movement through the chain (18) 15 It transmits to the transmission gear (20). The tensioning chain sprockets (19) in the mechanism on the other hand, by pre-tensioning, it dampens the vibrations caused by the movement of the chain (18). and prevents fluctuations in chain tension. The transmission gear (20) is mounted on through the output shaft (22) that runs along the transmission gear bearing (21) the star plate (23) Performing circular motion of the y2 axis, vertical 20 in rising and falling revolutions It enables the arms (24) to start the mixing process. With the effect of the specified system, the concrete The mixture can become homogenous in a very short time and is of high quality. It can reach the relevant area from the prepared concrete mixture outlet hopper (25). It can spill. 30
